Being an industry expert is not an easy task, one has to have diverse knowledge and complete understanding of every major and minor item they use in their project. Let’s take an example of Globe valve. Who on earth would not b familiar with this name particularly if they belong to engineering and plumbing industry world?
However, before you begin your search for the best globe valve manufacturers for your upcoming project, make sure you’re well aware of the basic components of it. Are you? If not, then the notion of writing this informative posts for readers like you hence fulfilled here.
Let’s jump down to learn what the main components of a globe valve are.
The Main components of Globe Valve
The components of globe valves are actually divided into three main types;
Globe – the globe bodies have both an inlet and outlet on the same axis which allows for a straight run of piping during installation.
Angle – While, the angle bodies comprise of inlet and outlet on perpendicular axes. This effectively makes the valve an elbow in the piping system.
Regardless of the body style, the body also contains internal trim components.
As the plug and stem slide up and down, the available flow area through the cage gets changed. Therefore, modulating the fluid flow rate.
The valve plugs are available in both balanced and unbalanced designs. Well, regardless of the plug design, it’s imperative to guide the plug to retain its stability and alignment throughout the entire stroke of the valve.
The plug and seat ring should be properly aligned as actuator force is applied to achieve the desired leakage class.

Let’s jump down to learn what the main components of a globe valve are.
The Main components of Globe Valve
The components of globe valves are actually divided into three main types;
Body Style
A sliding system valve assembly is made of a body and a bonnet. The two common body styles are;Globe – the globe bodies have both an inlet and outlet on the same axis which allows for a straight run of piping during installation.
Angle – While, the angle bodies comprise of inlet and outlet on perpendicular axes. This effectively makes the valve an elbow in the piping system.
Regardless of the body style, the body also contains internal trim components.
Trim components
The internal trim components of the globe valve are found in a sliding stem valve are the plug and stem assembly, the cage, and the seat ring. The plug and stem assembly is the only moving component in the valve body.As the plug and stem slide up and down, the available flow area through the cage gets changed. Therefore, modulating the fluid flow rate.
The valve plugs are available in both balanced and unbalanced designs. Well, regardless of the plug design, it’s imperative to guide the plug to retain its stability and alignment throughout the entire stroke of the valve.
The plug and seat ring should be properly aligned as actuator force is applied to achieve the desired leakage class.
Bonnet
The bonnet is attached to the valve body, and its removal enables access to the valve trim for maintenance. There are different styles of the bonnet which cater to different application temperatures. This primarily includes;- Standard bonnet
- Optional Extension bonnet
